Wak Burger Gangnam is a handmade burger shop in the Gangnam office district of Seoul. Patties are served on soft brioche buns, and the fries come out crisp on the outside and moist inside. Orders are placed at a kiosk next to the escalator, and at lunch the food took about 30 minutes to arrive. The basic set's burger feels small, and a greasy aftertaste lingers at the end.
